No response on opened port

az flag

I successfully installed a VPN script on my server and can see that it was configured to listen on port 54321 which is confirmed by sudo lsof -i -P -n | grep LISTEND.

The VPN is running, I see the port being listened to, but whenever I navigate to <ip_address>:54321 I get nothing besides a timeout.

Is there any further configuration needed on Ubuntu to allow traffic to/from port 54321? I have opened the port in my firewall and technically it should work.

Appreciate any advice, thank you.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
